Tomorrow I pick-up my Pedersoli Rolling Block in 45-70, plan is to have it re-bored to 50-90 among other customizing. First question is who to have do the re-bore? Internet has several 'smiths advertised......any experiences? Opinions?Thanks

I think it is a slightly crazy idea but it's your gun, your life, your money.

That said, I believe .50-90s in a Ped may have issues clearing the hammer's nose or the top corner of the block. You may have to do additional work to get the bullet in the bore. Might be mistaken but do your homework before you get carried away.

Might you be better off getting a new barrel fitted in 50-90 rather than a re-bore? Your gun, your vision . . . therefore, it's your decision.

You have been given some good advice. Stay away from a 50-90 in a Pedersoli roller. At best, you won't like it. At worst, you are in the process of spending a lot of money to cobble up a train wreck waiting to happen.

Longway around the barn to get to the house.... Would most likely be better just to get a 50-90 built gun to start with, unless you're getting that roller for 50$... Get ahold of Crossfire Oops here, he can tell you what all will need to happen besides a different extractor.Then if he doesn't want to tackle the job you'ld probably be smart to get ahold of Dave Casey or Wyoming Armory up in Cody and see if either of them want to take it on.

I have shot a friend's 50-140 Rolling Block in the past, so it can be and has been done. I honestly can't recall the modifications he needed to do to be able to load that cigar into the bore, though. Lee Shaver, or any other BPCR familiar gunsmith would be able to tell you.

suppose its a matter of anything can be done just a matter of cost......have other 45-70's and 50-70's are relatively common. Had been planning on talking to Lone Star but that tragedy puts me on a different road.

I never did get a chance to ask Dave WHY Pedersoli chose to MODIFY a perfectly functional classic design like they did, but their added .100" between Action Pin centers is just flat WEIRD, and so are some of the "Fitting Jobs" on their triggers and lock levers,......

You can take a BUCKET full of assorted original Roller parts, US, Spanish, Gypo, Argentine,.....and ASSEMBLE a working rolling block action, and many of us have.

...The Pedersoli is an aborted 'Stand off replica" with it's own individual geometries, dimensions and nuances,....

There it is

Don't want to muddy the water too much, but the gentleman who died recently, who did Rollers in Texas, opined that he could rebore a .45-70 Remington #5 to .50 with no difficulty. Of course, the barrel was one and an eighth across the flats.
